Collins COBUILD Dictionary of English, English/Japanese Digital Edition

COBUILD was a joint research project by Collins, a major UK dictionary publisher, and the University of Birmingham. The COBUILD Advanced Learner's English Dictionary, which was originally developed based on The Bank of English™, a corpus of roughly 650 million words, was a ground-breaking project to analyse and describe English as it was used.

JapanKnowledge has now updated the COBUILD Dictionary as a ‘Digital Edition,’ based on the Collins COBUILD Advanced Learner's Dictionary 10th edition, by adding, revising, and expanding entries, and by including Japanese translations of meanings, example sentences, and explanations specifically for Japanese learners.

The full-sentence definitions are a special feature of COBUILD, providing readers with a precise understanding of the meaning of words and phrases. This helps learners not only to build their vocabulary but also builds confidence in English by describing the meaning of the word using typical and authentic contexts in which the word is used by English speakers.
In addition, an audio button appears next to each word, allowing users to hear the word pronounced correctly by a native English speaker.
